Does samba provide a fuzzing mode that uses deterministic NTLMSSP_Challenge?
Hi,
Recently I want to fuzz samba systematically (instead of functional fuzzing like OSS-Fuzz/samba). However, the fuzzer acts like smbclient and needs to establish a connection with the samba server via NTLM authentication. The NTLMSSP_Challenge sent by the server is not deterministic, which can render the fuzzing based on previously captured traffic futile. Does samba provide a fuzzing mode that uses deterministic NTLMSSP_Challenge, or how can I directly bypass the authentication stage?
Thanks for your time.

...sely: If you try to connect manually to \\IP it says "Username or

Accessing a guest share from Windows 10 gives System error 5 on some computers
...Windows 10's Anniversary Update (14393) or Creators Update (15063) and there doesn't seem to be a correlation regarding that.
I tcpdumped both types of sessions, and these show that the Windows Client forcefully closes the TCP connection (NT_STATUS_CONNECTION_RESET) right after receiving `NTLMSSP_CHALLENGE` before a working client would send `NTLMSSP_AUTH` with a user.
I have checked setting `AllowInsecureGuestAuth` in the geristry without any effect.
Help!
Best regards

samba and the application of MS patch KB852004 - madness may follow
...64bit system I have works fine against the samba server.
A co-worker used a packet sniffer to watch connections to the server and
here is what he sent me:
From what I see, xxx.x.12.10 (the box that fails) is connecting to samba
server but is getting rejected. The packet is interpreted as
?NTLMSSP_CHALLENGE, Error: STATUS_MORE_PROCESSING_REQUIRED?. Then the
connection closes. So it doesn't look like a network issue, but rather an
authentication issue. For xxx.x.12.12, which works, the same error message
displays, but then xxx.x.12.12 sends the user name. 12.10 never sends the
user name....

[PATCH 0/10] NTLM patchset submission
Hello all,
as I promised some days ago here is NTLM (aka SPA, aka MSN) authentication
support patchset.
It contains common code in src/lib-ntlm directory, Samba compatible
NTLM password scheme and authentication mechanism itself.
All patches are against 1.0-test30.
Please take a look.
Best regards.
